REGENEBATIVE TIPPING FURNACE.

Application filed October 21, 1918.

m may concern .t lmown that simmer Mnunron cl the cpublic of France, of u .ltue de la l erme, Billane.) in the suid Republic, enncer, have invented certain new and use m eqtmeratlve l ipplng crehy declare the folcl an", and exact descripiiiml'lore, such. as will enable ti ed in the art to which it apperi use the same, reference boto the acconipauying drawings, and to letters or fig es of reference marked thereon, which form a part of this specification.

The in vol rti 'furnzmcs oi. furnace or t. heat regener gaseous cu. time illhe object or? the invention is to utilize the heat to be r eii'oct than usually, and on the th lrnd to enable each time when the current imrsed to readily substitute an inlet orifice :i'or an outlet orifice, and vice versa, both r the furnace body and for the regenerate; lhe orifices of the rogen craters and i i no furnace body are constructed according to the invention which 0 wt, g1

refers to high temperature Jl where the body of the irnace proper is attached to :1 tot. w ich inversions of the rents cti'ected from time to :lr ms the suh ect of my prior application lie trivalent, ijerial No, $330996, dated the 26th of r i pril, l i, there being no material junction between each outlet orifice and the corresponding inlet orifice, the joint being formed on v by the ambient air.

With tl'iese ob iocts in view, the invention consists oi a 'iplianccs which will be desoribei low and which are shown on the anner swing l iguz l. of the drawings is a longitudinal elevation, partly in section of a tipping furnace the r 'mcrators situated in the same i 7 Wu elements of the general urrai t O.) the furnace being provided. with i P luncttes which carry diaphragmr-i outlet :1 Hi

:h are arranged the inlet and Specification of Letters Patent.

Fig. 4 is a transverse half-section of the furnace body.

Fig. 5 is a detail view in vertical longitudinal section and to a larger scale, showing the diaphragms, on one of the regenerators and at one of the extremities of the fur nacc, and through which the hot air is admitted into the latter.

Fig. 6 is a front view of one of the lunettcs mounted on the furnace and shown in full lines in the same position as on Fig. 5, while the chain lines indicate the reverse position.

As will be seen from these drawings, at each extremity of the furnace proper a, there is placed a lunette b which can oscillate around an axis 0 below the orifice of the furnace, and which carries two diaphragms d and e, the first of which has an orifice with a cross section and a longitudinal section suitable for the admission of hot air into the furnace, while the orifice of the second one is suitable for the outlet.

A similar lunette f or f provided with two difierent diaphragms, one fortheinlet and one for the outlet, is mounted on each of the regenerators g, 9

It is thus sufficient to tilt the two lunettes of the furnace as well as the lunette of each of the regenerators which communicate direct] y with it through an air joint, in order that all the inlet and outlet orifices may have the new cross section and longitudinal section which are suitable when an inversion of current is efi'ected. Y v

The reversing device used is clearly cated in the drawings.

Each of the regenerators g, g located in the axis of the furnace, communicates with another regenerator h, h in which the air undergoes a first heating, and both of these regenerators h and h communicate with a reverser i which receives at its upper part, for instance, the air sent by theifan, while it communicates through its lower part with the chimney.

In its middle portion, the reverser is divided into two branches, 7', 70, one of which communicates with the regcuerator h and the other with the regenerator b and in each of these branches are placed two valves Z, m, or n, 0.

If, for instance, the valves m, and n are opened, and the valves Z and o are closed,

as indicated in Fig. 2, the air will pass, in order to enter the furnace, through. the regenerating chambers, k and g and the gaseous products will issue from the furnace nd pass through the regenerators g and h. he opposite will tel-2e place if the valves are ieced inthe' inversed position (see Fig. 1).

In the drawings, it is assumed that a furnace is heated by pitch. On each of the re generators, g and 9 there is accordingly mounted a heating; reservoir 32 for this new terial. and to which is connected :1 filter and a reservoir 1' of filtered pitch, which distributes that fuel through an admission pipe 8 and is provided with a. controlling cock t.

The lunettes provided with diaphragn s b, '6 7', f (see Figs. 5 and h) are sectors of cast iron furnished with sheet iron sockets (1', e suitably ined with refractory material in order to obtain an orifice of the desired section. These lunettcs swing around an axis 0 situated below the orifice of the furnace or of the regenerator to which they belong, sockets u being provided into which two workmen insert bars in order to make them swing gently during the inversions of the currents. At the top they are pro idcd, to the right and to the left, with a lug r which abuts against a pin to at the end of their stroke in one direction or the other. In or der to be able to fix them in the position to which they have been brought, their pivots and their abutment pins are screw threaded and provided with nuts,

The operation is as follows: If the valves Z and 0 (Fig. 2) are opened, and valves m and u are closed, air is directed to the hot regenerators 71 and f/ in series. The smaller opening (l of the lu'nctte 7" for regenerator f] at the left of Fig. l, as u'cli as the sn'iallga opening to the furnace of the similar lunette 7), placed in position. Valve t is opened to allow the flow of filtered pitch from the reservoir r througl'i pipe s into a, current of hot air from reg; irator ,1 into the furnace a. he pitch luirus in the furnace, and the hot; gaseous products of combustion issue from the opposi ends of the furnace through the largg'crorifices e (which have seriously been positioned) i h lunettes B and 7" These pi'i'ul'ucts oi combustion then pass to rcgcnerators and 22 through open valve 0 to the stack. When the positions of the veiveslmrt, n, 0, are reversed, assuming the positions shown in Fig. 2., the lunettcs i5, 7), 1",.are re cut ilt ii, and a like flow established at the opposite end of the furnace from a like roscrvoir, not shown.

Having thus dcscrihcd"my ii'ivcntion and. the hcst i'neaus 1 know of carrving the same into practical oii'ect, I claim l, A furnace having a. port at each cud, a regenerate? at each eud of lhe fur. are hav iup; ports omiosii'e the ports'ot the latter,

rscd; the how of pitch means for passing a gaseous, current through.

the furnace and regenerators by way of the ports, means for reversing the direction of said current, and diaphragms interposed between the ports of the furnace and regencretors, each having apertures of diiferent diameters adapted to be selectively arranged between the ports of the furnace and IQ'fit'r crators, for the purpose specified,

3. A. furnace having ports at its opposite ends, regenerators having ports opposite the ports of the furnace, means for passing a gaseous current through the furnace and re generators, means for reversing the direction of said current, and means whereby conduits of diii'ercnt diameters are brought into communication with the ports of the furnace and regenerators, for the purpose specified.

4:. A furnace having; ports at its opposite ends, regcncrators having; ports opposite the ports of the furnace, means for passing a gaseous current through the furnace and re generators, means for reversing the direction of said. current, means whereby two conduits connect the port of one regenerator with the one port of the furnace, and means whereby two conduits connect the other port or the furnace with the port of the other rcgenerator, the diameter of one pair of (7011. duits being greater than the diameter of the other pair of conduits, for the purpose specified.

A furnace having ports its opposite ends, regenerators having ports opposite ti ports of the finance, means for passing; a gaseous current through the furnace and generators, means for reversing; the (ii.

tion of said current, means whereby two disconnected oondiuts connect the port of one regenerator with one port oi the furnace,

and means wherel'z we discoiuiectcd couduits connect the other port of the Furnace with the port of the other reggcucrntor, the diameter of one pair of conduits being greatcr than the diameter of the other pair 01 conduits, for the purpose specified.

6, A furnace having ports at its opposite ends, l'fi Qf -ifiltllfil'fi having ports opposite the ports of the furnace, means for passing a gaseous current through the furnace and re generators, means for reversing the direction of said current, means wherelrv two dis connected conduits connect the purl of one regenerator with one port of the furnace,

and means whereby twedisvonnected conduits connectthe other port 01 thefurnace with the port 'of the other regenerator, and

5 means for feeding a carbonaceous fuel to the hiatus in each pair of conduits.

In testimony that I claim the foregoing as my invention, I have signed my name in 'presenve of two snbsm'ibing Witnesses.
